The device encryption must be suspended before flashing the computer BIOS and when a motherboard or a computer drive replacement is expected.Since USB drive is used widely to save personal data and business data, the security of USB is talked widely. Ensure that any backed-up recovery key is accessible from another computer or phone: Finding your BitLocker Recovery Key in Windowsĭevice encryption should be suspended before the computer is serviced on-site or returned to a service center. The device decryption should only be used before restoring a Windows image.īefore making a change that might trigger a BitLocker Recovery Key, ensure that a recovery key was safely backed up before activating BitLocker protection. Also, decrypting a drive is time-consuming: Microsoft estimates it takes approximately 1 minute per 500 MB of drive space. The process only takes a few seconds to complete and ensures that the drive content is still protected from unauthorized access yet allows computer repair/maintenance to occur.ĭecryption permanently removes the protection and makes the content accessible to anybody who can access the drive. The suspension provides a quick option to temporarily disable the protection on the computer drive for service. ĭifference Between Suspending and Disabling Encryption If you want to stop encryption during OOBE and disable it permanently, use Manage-bde Off. Modifying the registry key is only effective when applied to an image before installing Windows. KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BitLocker The automatic BitLocker Device Encryption process can be prevented by changing the registry setting: Preventing or disabling the device encryption should only be used in servicing scenarios. To resume device encryption, use: Resume-BitLocker -MountPoint "C:" Because the RebootCount parameter value is 0, BitLocker encryption remains suspended until you run the Resume-BitLocker cmdlet. This command suspends BitLocker encryption on the BitLocker volume that is specified by the MountPoint parameter. Suspend-BitLocker -MountPoint "C:" -RebootCount 0 Manage-bde -status : (replace with the drive letter, e.g., “C”) Open a PowerShell or Terminal window as Administrator and type: As part of this preparation, BitLocker device encryption is initialized on the Operating System drive and fixed data drives.Ĭheck, Suspend/Pause, and Prevent the Device Encryption BitLocker Device EncryptionĪfter a clean installation of Windows 11 or Windows 10 is completed and the out-of-box experience (OOBE) is finished, the computer is prepared for first use.
